what happens If I remove mysql-bin.index file?

Question

Because of the file storage full, we are removing mysql bin log files.

Accidentally, we removed mysql-bin.index file.

What happens if I remove mysql-bin.index file?

These below are my DBMS info. Thank you.

MariaDB 10.4

If you erased all the binary logs, the mysql-bin.index can also go.

Do you still need binary logging ? You must restart MariaDB, and the mysqld process will recreate mysql-bin.index it for you.

If you no longer want binary logging, you must comment out log-bin from the MariaDB config file. You still need to restart MariaDB.
